Works nicely. There had been a slight issue with the version that got automatically installed yesterday - with the update today the old proxies got restored.
To all people ranting here, please calm down and better check out the corresponding github page
https://github.com/foxyproxy/browser-extension

I had been a bit surprised yesterday and then just checked that site - the README already explains it and more details are under issues.

You can restore the missing settings. Go to the version selection at https://addons.mozilla.org/ru/firefox/addon/foxyproxy-standard/versions/, install version 7.5.1, and disable updates until the developer fixes the issue.

Пропавшие настройки можно восстановить. Зайдите в выбор версии https://addons.mozilla.org/ru/firefox/addon/foxyproxy-standard/versions/ установите 7.5.1 и отключите обновления пока разработчик не исправит проблему.

Пользуюсь больше года! Отличное расширение! выручает постоянно.

amazing

I prefer the user interface of the standard version to the basic version, even though it hasn't been updated in three years.

Thanks for your incredible work, this extension helps me all the time with easy to use and simple interface. can please look into why when it's on rules mode the `options` requests won't go through proxy. `post` and `get` requests are fine the only problem is with `options` requests. thanks again
